Electrical connector

Abstract

A connector for holding a linear conductor by a first contact portion and a second contact portion is provided. The linear conductor is inserted through an insertion portion. The first contact portion is formed in a pressing portion configured to be deformed elastically to press the linear conductor against the second contact portion. The second contact portion is formed in a fixed portion which is not deformed elastically and the second contact portion has at least one edge portion.

 wherein the second contact portion is formed in a fixed portion which is not deformed elastically and the second contact portion has at least one edge portion, the edge portion is formed at an edge of a punched-out region of the second contact portion. 
 
     
     
       2. The electrical connector according to  claim 1 , further comprising:
 a front leg and a rear leg which are provided at a front position and a rear position in an insertion direction, respectively; and 
 a connecting portion which connects the front leg and the rear leg to each other, wherein: 
 the second contact portion is provided in the connecting portion. 
 
     
     
       3. An electrical connector for holding a linear conductor inserted therein, comprising:
 a front guide portion including an insertion portion; 
 a front leg and a rear leg which are provided at a front position and a rear position in an insertion direction, respectively; 
 a connecting portion which connects the front leg and the rear leg to each other; and 
 a pressing portion which is configured to press the linear conductor against the connecting portion by a surface when the linear conductor is inserted into the electrical connector, wherein 
 the surface is not a distal edge of the pressing portion, 
 the connecting portion has at least one edge portion, 
 the edge portion includes a longitudinal edge portion, the edge portion is formed at an edge of a punched-out region of the connecting portion, and 
 the surface of the pressing portion and the edge portion are configured to hold the linear conductor between the surface of the pressing portion and the edge portion. 
 
     
     
       4. The electrical connector according to  claim 2 , wherein the edge portion includes a lateral edge portion which extends so as to intersect with the insertion direction when viewed from a side of the pressing portion. 
     
     
       5. The electrical connector according to  claim 4 , wherein
 the connecting portion branches into two portions at a front-rear halfway position in the insertion direction, and 
 the lateral edge portion is provided in a portion from which the two portions branch off. 
 
     
     
       6. The electrical connector according to  claim 4 , wherein the connecting portion includes a portion that is inclined so that the lateral edge portion is convex toward the pressing portion. 
     
     
       7. The electrical connector according to  claim 1 , wherein the edge portion includes a longitudinal edge portion which extends in the insertion direction when viewed from a side of the pressing portion. 
     
     
       8. The electrical connector according to  claim 7 , wherein the longitudinal edge portion is curved so as to be convex toward the pressing portion. 
     
     
       9. The electrical connector according to  claim 7 , wherein the longitudinal edge portion is respectively provided on both of left side and right side of the insertion direction when viewed from the side of the pressing portion. 
     
     
       10. The electrical connector according to  claim 1 , wherein
 the pressing portion is a plate spring portion that is inclined with respect to the insertion direction so as to come closer to the edge portion as a position goes toward a tip portion of the pressing portion, and 
 a gradient of the tip portion of the pressing portion is smaller than that of a base portion thereof. 
 
     
     
       11. The electrical connector according to  claim 1 , wherein the electrical connector is made of a sheet-metal part. 
     
     
       12. The electrical connector according to  claim 3 , wherein the edge portion includes a lateral edge portion which extends so as to intersect with the insertion direction when viewed from a side of the pressing portion. 
     
     
       13. The electrical connector according to  claim 12 , wherein
 the connecting portion branches into two portions at a front-rear halfway position in the insertion direction, and 
 the lateral edge portion is provided in a portion from which the two portions branch off. 
 
     
     
       14. The electrical connector according to  claim 12 , wherein the connecting portion includes a portion that is inclined so that the lateral edge portion is convex toward the pressing portion. 
     
     
       15. The electrical connector according to  claim 3 , wherein the edge portion includes a longitudinal edge portion which extends in the insertion direction when viewed from a side of the pressing portion. 
     
     
       16. The electrical connector according to  claim 15 , wherein the longitudinal edge portion is curved so as to be convex toward the pressing portion. 
     
     
       17. The electrical connector according to  claim 15 , wherein the longitudinal edge portion is respectively provided on both of left side and right side of the insertion direction when viewed from the side of the pressing portion.
